    Assess Sclerotinia risk to assist crop planning

    Plant pathologists have found that some pulse species are more susceptible than others to the damaging diseases Sclerotinia white mould and Sclerotinia stem rot. The three species of the pathogen found in pulse crops are Sclerotinia sclerotiorum, S. minor and S. trifoliorum. Sclerotinia’s hosts include canola, chickpeas, lentils, faba beans, lupins, vetch, field peas and pasture and broadleaf weeds. Wheat, barley and oats are not hosts. NSW Department of Primary Industries and Regional Development senior plant pathologist Dr Kurt Lindbeck says narrow-leafed lupins and chickpeas are highly susceptible to the disease.

    Battle with rust swings in growers’ favour

    The secretive virulence genes that rust pathogens need to cause epidemics can now be identified en masse using a new CSIRO technique that provides the foundation for a more-rapid way to keep tabs on changes in rust virulence on wheat cultivars

    10 years of discovery and impact celebrated

    In April, Curtin University’s Centre for Crop and Disease Management celebrated its 10th anniversary. The celebration underscored the Centre’s role in promoting food security and agricultural sustainability, marking a milestone of excellence and impact in the field. Featured addresses from John Woods, chair GRDC and Professor Harlene Haines, Vice Chancellor of Curtin University, both praised the CCDM’s pioneering research in crop disease management and collaborative approach with industry partners.

    Fight against cereal rusts enters a new era

    The Australian Cereal Rust Control Program has entered a fifth phase, developing knowledge and technologies to better understand the pathogen and improve rust resistance in cereals. Here is a summation of the new work in progress.

    FAW’s ability to adapt putting more crops at risk

    The word ‘challenge’ dominated talk at the National Fall Armyworm (FAW) Research, Development and Extension Symposium in Brisbane in April. It is now in Victoria and it has also confirmed its presence in New Zealand. It is one of the most challenging and confronting pest management issues for growers.

    Automated detection takes guesswork from fungicide response

    BioScout’s next-generation spore traps leverage automated microscopy and machine learning to provide near real-time insights into airborne fungal disease threats. This allows growers to take targeted action and optimise spray programs, including through a newly launched automated surveillance network

    Disease outlook and managing increased risk

    GRDC Research Updates have foreshadowed a heightened risk of disease in 2024, while providing advice on the steps to take to minimise impact on grain yield. Providing a cereal disease outlook, plant pathologist Dr Grant Hollaway from Astute Ag said there was risk of yield losses from diseases including Septoria tritici blotch in wheat, net form of net blotch in barley and rust pathogens in both cereals.

  • Barley grass stripe rust variants characterised by increased virulence

    Barley grass stripe rust variants characterised by increased virulence

    BGYR (barley grass stripe [yellow] rust), was first detected in Australia in 1998, predominantly affecting wild barley grass weed species. Through comparative greenhouse studies, the Plant Breeding Institute established that the BGYR+ variant has shown increased virulence on several barley varieties at seedling growth stages.

  • The AFREN creed

    The AFREN creed

    Creeds can be powerful beliefs to live by and when it comes to dealing with fungicide resistance the Australian Fungicide Resistance Extension Network have developed the powerful Fungicide Resistance Five. A checklist, underpinned by science, this creed is a reminder as to how to mitigate the threat of resistance. Growers are encouraged to keep it top of mind.
